GBPUSD breaks through a Thomas Demark Resistance trend targeting MAXIMUM 1.57 area..
However...
The MINIMUM target for Thomas Demark as around 1.5450, around the current area, and we have a Gartely Pattern to be completed any time around 1.5450 as well.
In addition, a resistance structure between 1.5450 and 1.56 would make the pair more closer to start heading south to 1.52 area to 1.5050.
That is my personal view from a technical point of view and not a recommendation by any mean to buy or sell.
Have a nice trading
